I try to program a steering for a Logo Boost Model. Motor B spins a certain angle and the steering works. To get it running the model - the app - needs to know the current position of the wheels in order to spin the motor correctly. I created several macros where i decide on, and set, a variable. I initialize the model by setting the variable in the main screen of the program interface. But if I go into my steering macros this varable is not known. Instead i can set the variable within. It means, I cannot have a global variable which can be read and set from within macros?
